Do the Biblical authors agree on who God is? In many cases they do, in others they do not.
Most biblical scholars say that the Bible was written by a diverse group of people with differing views and opinions about political and social issues (one only need look at some of the differences between the Hebrew Bible with it’s nationalistic focus, to the New Testaments pacifist ethics.)
As the Oxford Companion to the Bible (edited by leading Princeton/Harvard scholars Bruce Metzger and Micahel Coogan) asserts: “The Bible thus speaks with many voices, and, from the time of its emergence as an authoritative sacred text, readers and interpreters have noted its many repetitions, inconsistencies, and contradictions.”
